Email notifications could be better

The default email notifications from BuddyPress are ugly and are normally sent to spam for most people. There are a couple of ways it could be better:

– Integrate plugin “Welcome Pack” email component by default; greatly prettifies the default notifications
– Change the From: address from the default server’s address. This could be the name of the member that triggered the notification (i.e. whomever sent you a message or mentioned you, etc.), but from noreply@yoursite.com. I’m saying Member Name (Community Name), from noreply@yoursite.com.

If the second suggested change is room for another plugin, can someone point me to where one could start?
